FIELD: chemical industry. SUBSTANCE: claimed invention describes preparation of town diesel fuel containing not greater than 0.005 wt% sulfur and not greater than 20% aromatic hydrocarbons by hydraulic cleaning of diesel fractions at elevated temperature and pressure in the presence of alumo-cobalt-molybdenum layers in admixture with elementary sulfur and alumo-nickel-molybdenum catalysts preactivated in hydrogen-containing gas at temperatures form 350 to 400 C. The ratio of alumo-cobalt layers and alumo-nickel-molybdenum catalysts depends on the content of sulfur and aromatic hydrocarbons in the feedstock and is determined by formula: 1+15*S/A wherein S denotes content of sulfur in the feedstock, wt%; A denotes content of aromatic hydrocarbons in the feedstock. EFFECT: greater degree of hydrorefining.
